Minjoo Larry Lee Professor, University of Illinois Urbana-ChampaignDate: April 10, 2025 Time: 11:00 AM - 12:00 PM ET Location: Building 12, Room 0168 (MIT.nano Basement Teaching Space)RegisterABSTRACTIn this talk, Prof. Lee will describe recent work in his group on molecular beam epitaxy (MBE) growth for visible photonics applications. First, he will describe efforts to integrate red AlInGaP-based laser diodes on a SiN/Si photonics platform for trapped ion qubit technology. Through a combination of selective and non-selective III-V growth, he show that InP quantum dots grown in “pockets” are a promising active region material for butt-coupled visible gain. Next, Prof. Lee will discuss his groups efforts to demonstrate solid-state image intensifiers for night vision applications. He uses InGaAs avalanche heterojunction phototransistors with an intrinsic gain feedback mechanism to directly drive visible AlGaInP LEDs without op amps or any external circuitry. Prof. Lee will show sensitivity to 1.55 µm light at incident intensity down to nW/cm2, close to the level of nightglow.BIOGRAPHYMinjoo Larry Lee received his bachelor’s degree from Brown University and his Ph.D. from MIT, both in materials science. He started his faculty career at Yale University as an assistant professor in EE, and he is now with the ECE department at UIUC, where he is a professor, Intel Alumni Scholar, and Director of the Nick Holonyak, Jr. Micro and Nanotechnology Laboratory. His research focuses on epitaxial materials and devices, and he is the author of over 190 papers and conference proceedings. He is an Optica fellow, and his research recognitions include the IBM faculty award; North American conference on MBE Young Investigator Award; DARPA Young Faculty Award; NSF CAREER award; and the IEEE Electron Device Society George E. Smith award. His advisees have won 14 best presentation prizes at international conferences, and he has been honored for his teaching in circuits, electromagnetics, and IC fabrication.

Join us for a Sustainability Lunch Series featuring Jamie Saxon, Senior Director of Sustainability and External Innovation at Inari. Inari is redefining the future of agriculture through SEEDesign™, leveraging cutting-edge breeding technologies to create nature-positive seeds that enhance sustainability and resilience in our global food system.Through a powerful combination of AI-powered predictive design and multiplex gene editing, Inari is unlocking the full potential of seeds—helping farmers grow more food with fewer resources. This conversation will explore how innovative seed technologies can drive climate resilience, reduce environmental impact, and revolutionize the way we think about agriculture.

The engineering skills you are learning can be valued in ways you can’t imagine! Join Megan Lee as she walks through her career journey from being an entry-level engineer designing innovative new medical device products to directing global marketing strategies for robotics and digital surgeries. Discuss what engineering and leadership skills made her stretch assignments successful and her career goals possible. And learn the inside scoop on why Engineers are uniquely useful in unexpected leadership roles.

The refining of critical metals such as nickel and cobalt from waste can be done much more efficiently with a new electro-extraction technology. Megan O'Connor is co-founder of a company focused on sustainable, domestic production of critical metals. She will discuss the transformative potential of the Oyster, an electro-extraction device that is small enough to locate at the source of recycling, manufacturing, or mining, meaning waste metals don’t have to be shipped to stand-alone refining plants.Register for this MIT Horizon webinar.This is a series of live events in partnership with MIT Startup Exchange.

Have some fun(nel) on a tunnel or sun(nel) walk! Join us for a 30-minute volunteer-led walk either through MIT's famous tunnel system or around Killian Court. As the weather gets warmer, walk leaders may choose to take the group outside. Is the weather warm and you missed the start? Find the group on Killian Court and join in!Location details: Meet in the lobby under the “Belonging + Community” banner. Location photo below.Sun(nel) Walk Leaders will identify themselves by holding a white at the meeting location.Prize Drawing: Attend a walk and scan a QR code from the walk leaders to be entered into a drawing for a getfit canvas boat tote bag at the end of the getfit challenge. The more walks you attend, the more entries you get. Winner will be drawn and notified at the end of April. Winner does not need to be a getfit participant.Disclaimer: Tunnel walks are led by volunteers. In the rare occasion when a volunteer isn’t able to make it, we will do our best to notify participants. In the event we are unable to notify participants and a walk leader does not show up, we encourage you to walk as much as you feel comfortable doing so. We recommend you check this calendar just before you head out!Getfit is a 12-week fitness challenge for the entire MIT community. These tunnel walks are open to the entire MIT community and you do not need to be a current getfit participant to join.
